DEFINITIONS 527 scious or unconscious, since in the act of apperceiving a new content a prepared combination of contents unfail- ingly emphasizes those qualities or motives which appear to belong to the subjective content Hence a selection or judgment takes place which excludes the irrelevant. As to what is, and what is not, relevant is decided by the already orientated combination or constellation of contents. Whether the attitude's objective be conscious or unconscious is immaterial to its selective effect, since the choice is already given a priori through the attitude, and therefore follows automatically. It is useful, however, to distinguish between conscious and unconscious, since the presence of two attitudes is extremely frequent, the one conscious and the other unconscious. Which means to say that the conscious has a preparedness of contents different from that of the unconscious. This duality of attitude is particularly evident in neurosis. There is a certain kinship between the concept of attitude and the apperception concept of Wundt, though with this difference, that the idea of apperception includes the process of relating the already prepared content to the new content ta be apperceived, while the concept of attitude relates exclusively to the subjectively prepared content. Apperception is, as it were, the bridge which connects the already present and prepared content with the new content} the attitude being, in a sense, the end- pier or abutment of the bridge upon the one bank, while the new content represents the abutment upon the other bank. Attitude signifies an expectation, an expectation always operates selectively—it gives direction. The presence of a strongly toned content in the field of cqn- sciousness forms (sometimes together with other contents) a certain constellation which is synonymous with a definite attitude, because such a conscious content favours the perception and apperception of everything similar,
